IMPRQVEMENT IN TRUSSES.

Specification forming part of Letters Patent No. 138,640, dated May 6,1873; applic ion filed April 30, 1873. I

To all whom it may concern:

Be it known that I, GEORGE WILSON GREGORY, of Syracuse, in the county ofOnondaga and State of New York, have invented a certain new and usefulTruss and Fastening Attachment.

The first object of my invention is to ena ble the pad to be adjustedreadily on the trussplate; and it consists in providing the trussplatewith a series of end and central slots, from one to the other of whichpads of various desired shapes may be applied, and the pad working inconnection with this truss plate when adapted for hernia has slots atabout right-angles to the slots in the plate. The second object of myinvention is to provide an attachment for readily connecting anddisconnecting the straps and truss-plate; and it consists in a plate orframe provided with suitable buckle-like tongues to hold the straps orbands, and. with a hook, projection, or opening to engage a slot,opening-hook, or post on the truss-plate or supporter andI do herebydeclare that the following specification taken in connection with thedrawing furnished and forming a part of the same, is a clear andaccurate description thereof.

Figurel is an outside view of the trussplate; Fig. 2, a horizontalsection of the same Fig. 3, a view of the back of the pad as adapted forhernia. Fig. 4 is a longitudinal section of the same. Fig. 5 is a viewof the fastening attachment; Fig. 6, a side view with buckle-liketongues upturned Fig. -7, a view of a tongue removed from the plate.Fig. 8 is amodified form of fastening, having an opening instead of ahook Fig. 9, aview of part of a strap with a piece attached to receivethe hook represented by Fig. 1.0.

A represents the truss-plate, made preferably of hard India rubber ormetal, and provided with ribs or projections to bear against the person,in order to prevent the plate from slipping and provide for ventilation.This truss-plate is provided with vertical slots a a atthe ends, andwithcentral slots to. The slots a are to receive the screw or screws thatsecure pads adapted for hernia, and in form substantially as shown inFigs. 3 and 4, and the central slots are to provide for the attachmentof umbilical pads, which are usually hemispherical. In addition tothese. ertical slots, the truss-plate has either slots, s shown at b, orhooks, as shown at c, to rec ve the hook of or engage the openingin efasteningplate. The pad B is preferaj y perforated where it bearsagainst the perso as at f; and its back is provided with slots out atright angles with slots in the truss-pl te when the two are in position.Under ese slots is placed a supporting-piece, d, fo the head of the bolt4, the screw-shank of hich passes through the slot in the pad, an alsothrough the vertical slot of the truss-p te from the ribbed side, andWhen'in such 1 osition and properly adjusted thepad is con ed by meansof a thumb-nut, e, which is t rned on said screw and against a washerthat a ears against the back of the truss-plate. Th plateA when providedwith the slots, as scribed and shown, admits of its being use herniatruss or for right or left nd, and an umbilical truss; or Without paused as a supporter. The fast ment consists of a frame, G, of providedwith buckle-like ton turn on the frame, and with a 4 and 5, or itsequivalent, (a Fig. 8. The tongues turn on th of these fastenings areusually truss-plate, and the buckle-like ongues con fine and hold thestrap, which i passed about the body, and the end of the trap that ispassed between the thighs. Th back end of the last-mentioned strap isprefer bly provided with a hook, I, (see Fig. 10,) an this hook isuitable form, es H, which ok, 1), Figs. opening, 0,) frame. Two ed witheach engaged with an opening in a pi cc of leather,

i, or other material, secured to r e outside of the. strap J whichpasses ab t the body. The fastening, when provided wi c a hook, as at b,is engaged with the truss-pla through the openings 1) made in thetruss-p1 e, or a plate attached to such truss-plate, (1 when thefastening is provided with the u ening, as at c, Fig. 8, then a hook, c,is to be ecured to or made to project from the back f the plate. Thefastening-plate may be p vided with projections g to bear against thtrussplate, in order to provide for additi al leverage and press the padclosely to th person, and also to assist in preventing t I truss-platefrom being overturned.

I do not desire to confine myself to bucklelike tongues of the formshown, as any other well-known tongues may be employed instead. Nor do Iwish to limit myself to the particular shape of hook or opening, asother shapes may be used.

By means of this fastening the truss-pad may be quickly fitted to theperson, and be readily removed. The slots a at the center of thetruss-plate might be of other shape than that shown, and one slot oropening might be sufficient for securing the umbilical pad.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A truss-plate provided with the series of central and end openings,substantially as described, to provide for the attachment of pads, asset forth.

2. The corrugated truss-plate provided with the long vertical openingsat its ends for attachment of a pad or pads.

3. The combination, with the trussplate provided with the vertical endand central slots, of the pad provided with the transverse slots andwith a screw-connecting device, substantially as described.

4. A det achable truss-fastenin g attachment, composed of a plate orframe provided with buckle-like tongues for confining the straps, andwith a hook or equivalent to engage the truss-plate, substantially asdescribed.

5. A detachable truss-fastenin g attachment composed of a plate or frameprovided with buckle-like tongues and with a hook or equivalent to engage with the truss-plate, and with a projection at the back of theframe to bear against the other side of the truss-plate, for the purposedescribed.
